我厂机械车间张万林、安邦绂等两同志改进一种抗振强力镗刀,经使用证明,效果良好,现介绍如下供各有关兄弟厂工人同志参考。抗振强力镗刀的几何形状如附图所示,刀片材料用BK_6。它有如下特点:1)前角大(γ=12°),在加工过程中切削力显著下降,从而节省功率。2)主偏角大(=75°),因此径向切削力大大减小,保证在切削过程中不
I plant mechanical workshop Zhang Wanlin, An Bangtao two comrades to improve a kind of anti-vibration strength boring knife, the use of proof, the effect is good, are presented below for reference to the brothers factory workers gay. Anti-vibration strength of the boring knife geometry shown in the figure, the blade material BK_6. It has the following characteristics: 1) Large rake angle (γ = 12 °), the cutting force in the process significantly decreased, thus saving power. 2) The main declination (= 75 °), so greatly reduce the radial cutting force to ensure that the cutting process is not
